    <h1>Dynamic components</h1>
    <p>The dynamic components provides the means of observing/manipulating
      components that are hidden in a sub-circuit on a higher level. Example:
      You have placed a led in a circuit named <strong>MyNiceCircuit</strong>.
      Now you use <strong>MyNiceCircuit</strong> as sub-circuit in the circuit
      named <strong>MyToplevel</strong>. Simulating in <strong>MyToplevel</strong>
      will hide your led, hence you have no means to see if the led in <strong>MyNiceCircuit</strong>
      is lighting up or not. The dynamic components help here by providing the
      possibility of putting an image of the led on the sub-circuit symbol of <strong>MyNiceCircuit</strong>.
      To add dynamic components to the sub-circuit symbol of <strong>MyNiceCircuit</strong>,
      you have first to open the&nbsp;<a href="../subcirc/sub-appear.html">appearance editor</a>
      of the circuit <strong>MyNiceCircuit</strong>. Than you click on the <img
        src="../../../../icons/dynamic_component.png" alt="dyncomp" title="dyncomp">-tool
      icon. A window will open listing all the available dynamic components, and
      you can select which one to show in the appearance of your sub-circuit
      symbol. Note that the dynamic components feature is a recursive property.
      This means that if you have a hierarchical structure, it will show all
      possible dynamic components available down from the current sub-circuit.</p>
    <p>Currently following tools support dynamic components:</p>
